One of the largest, most spectacular and yet easily accessible fortresses in the county is Klis, planted precariously on sheer cliffs just inland from Split. There’s an excellent view of this fortress from the highway that connects Split with the A-1 autocesta. Partially restored and now an outdoor museum, the fortress is well signposted from the road. It will take you at least an hour to explore the fortress and soak in the great views in every direction.There is a café right below the fortress. Klis has had a long and colorful history. It was first mentioned in written records in the first half of the 10th century. In the 13th century the Mongols invaded the area but never succeeding in taking the fortress. The Ottoman Turks captured it in 1537. Local nobles succeeded in retaking Klis, but only for a few weeks, in 1596. The Venetians finally evicted the Turks for good in 1648. When you visit Klis you will see why it was fought over so fiercely. Anyone occupying the fortress could control passage through the rather narrow mountain pass from the coast to the hinterland. The HBO series Game of Thrones has also been filmed in Klis.
